Clinical trials

The goal of this study is to obtain safety data, establish dose parameters, and effectiveness of treatment for the SpectraCure P18 System with IDOSE®, together with verteporfin for injection (VFI) as photosensitizer, for the treatment of primary localized prostate cancer. The study will be divided into two parts, with Phase I, dose-escalation, to study safety and establish an effective light dose, followed by Phase II, cohort expansion, to evaluate clinical efficacy and confirm safety/tolerability. The subjects will be followed for a period of 18 months to determine the primary outcome. The long-term follow-up is an additional 18 months, i.e. a total of 36 months. Interstitial Photodynamic Therapy (PDT) will be performed during general anesthesia. Optical fibers will be inserted into the prostate with a transperineal approach using transrectal ultrasound guidance. The intent is to deliver an adequate light dose throughout the prostate. Subjects will receive VFI intravenously, approximately 60-90 minutes prior to light delivery.

The rationale for the study is to obtain safety and efficacy data as well as to establish dose parameters for the SpectraCure P18 System with IDOSE®, with verteporfin for injection (VFI) as photosensitizer for the treatment of recurrent prostate cancer.
